Sesame Allergies on the Rise in U.S.

Sesame Seed Allergy Now Among Most Common Food Allergies

continued...

The findings suggest that tree nut-allergic children with unexplained hives, eczema, or other allergy symptoms might want to visit their allergist to determine if they’re allergic to sesame as well, the doctors say.

But a third study showed that standard skin and blood testing for food allergies “doesn’t predict whether a child has true sesame allergy,” says Permaul Perdita, MD, also of Children’s Hospital Boston.

“The only way to really tell is to give them sesame seeds and see if they have a reaction,” she says.

Such testing needs to be performed under medical supervision because there is a chance that the patient could have a potentially life-threatening anaphylactic reaction, Perdita tells WebMD. “What we really need is a better blood or skin test.”
